Chithunzi cha ASTM A106
Mtundu wa chitoliro: chitoliro chachitsulo chosasinthika.
NKukula kwa chitoliro cha ominal: Imakwirira chitoliro chachitsulo chosasunthika kuchokera ku DN6-DN1200 (NPS1/8-NPS48).
Makulidwe a Khoma: Makulidwe a khoma amafunikira kuti akwaniritse zofunikira za Gulu 1 laASME B36.10M.
Gawo la ASTM A106
ASTM A106 ili ndi magawo atatu a chitoliro chachitsulo: Gulu A,Gulu B, ndi Grade C.
Kusiyanitsa kwakukulu pakati pa magulu atatuwa ndiko kupanga mankhwala ndi makina.
Zida za ASTM A106
Chitsulocho chiyenera kuphedwa chitsulo.
Chitsulocho chimapangidwa pogwiritsa ntchito njira yoyamba yosungunuka, yomwe ingakhale yotseguka, yoyambira-oxygen, kapena ng'anjo yamagetsi, mwinamwake yophatikizidwa ndi degassing kapena kuyenga.
ASTM A106 Njira Yopangira Chitoliro Chopanda Zitsulo
Chitoliro chopanda chitsuloamapangidwa m'njira ziwiri: ozizira-koka ndi otentha-kutha.
DN ≤ 40mm chitoliro chachitsulo chosasunthika chingakhale chozizira kapena chotentha.
DN ≥ 50mm chitoliro chosasunthika chachitsulo ndichotentha.
Chithandizo Chotentha
Chitoliro chachitsulo chotentha cha ASTM A106 sichifuna chithandizo cha kutentha.
Machubu achitsulo osasunthika a ASTM A106 ozizira amayenera kutenthedwa ndi kutentha ≥ 650°C.
Chemical Composition
ASTM A106 Grade A, Grade B, ndi Grade C mu mankhwala a kusiyana kwakukulu ndi kusiyana pakati pa zomwe zili mu C ndi Mn, zomwe zili muzinthu zina m'magulu osiyanasiyana zingakhale ndi kusiyana pang'ono, koma nthawi zambiri kuwongolera osiyanasiyana otsika.
Mechanical Properties
Kutalika kocheperako mu 2 in. (50 mm) kudzatsimikiziridwa ndi equation iyi:
inchi-pounds:
e=625,000A0.2/UO.9
Magawo a Sl:
ndi = 1940A0.2/U0.9
e: kutalika kochepa mu 2 in. (50 mm), %, kuzungulira kufupi ndi 0.5%
A: gawo lagawo lachitsanzo choyesa kukangana, mu2(mm2）kutengera m'mimba mwake kapena m'lifupi mwatchutchutchu ndi makulidwe a khoma,yozungulira mpaka 0.01 inchi yapafupi2(1 mm2).
Ngati dera lowerengedwa motere ndilofanana kapena lalikulu kuposa 0.75 in2(500 mm2), ndiye mtengo wake ndi 0.75 in2(500 mm2) zidzagwiritsidwa ntchito.

Pulogalamu Yoyesera
ASTM A106 ili ndi tsatanetsatane wa kapangidwe ka mankhwala, kusanthula kwamafuta, zofunikira zamakina, zofunikira zopindika, kuyesa kosalala, kuyesa kwa hydrostatic, komanso kuyesa kosawononga magetsi.
Chemical Composition / Heat Analysis
Heat Analysis ndi njira yomwe imagwiritsidwa ntchito kudziwa zomwe zili muzitsulo zamtundu uliwonse kuti zitsimikizire kuti kapangidwe kake kazinthu zilizonse kumakwaniritsa zofunikira za ASTM A106.
Kutsimikiza kwa kapangidwe ka mankhwala kumatengera kusanthula kwamafuta.Cholinga chachikulu ndi zomwe zili ndi zinthu za carbon, manganese, phosphorous, sulfure, ndi silicon, zomwe zimagwirizana kwambiri ndi zomwe chitolirocho chimapanga.
Zofunikira za Tensile
Machubu ayenera kukwaniritsa mphamvu zokhazikika, mphamvu zokolola, ndi zofunikira za kutalika.Izi zimatsimikizira mphamvu ndi kulimba kwa chubu pa kutentha kwakukulu.
Zofunika Kupinda
Mayeso opindika amagwiritsidwa ntchito poyesa kulimba komanso kusinthika kwa pulasitiki kwa machubu akakumana ndi zovuta zopindika kuti atsimikizire kudalirika kwa chubu pakuyika ndikugwiritsa ntchito.
Mayeso a Flattening
Mayeso a Flattening amagwiritsidwa ntchito poyesa kukhazikika komanso kukana kusweka kwa machubu achitsulo.Mayesowa amafuna kuti chitolirocho chiphwanyidwe kumlingo wina popanda kusweka kuti atsimikizire mtundu wa zinthuzo komanso kuyenerera kwaukadaulo waukadaulo.
Kuyesedwa kwa Hydrostatic
Kuyesa kwa Hydrostatic ndi gawo lofunikira pakuwunika mphamvu yonyamula chitoliro chachitsulo pogwiritsa ntchito kukakamiza kwapamwamba kuposa komwe kumafunikira ndi muyezo kuti muwonetsetse kukhulupirika kwake komanso kusatulutsa kutayikira.
Nondestructive Electric Test
Nondestructive Electric Test (monga akupanga kuyezetsa kapena electromagnetic kuyezetsa) ntchito kuzindikira mkati ndi pamwamba zolakwika monga ming'alu, inclusions, kapena mabowo mu zitsulo machubu kuonetsetsa khalidwe la mankhwala.
Dimensional Tolerances
Misa
Unyinji weniweni wa chitoliro uyenera kukhala mumtundu wa97.5% - 110%za misa yotchulidwa.
Mapaipi mu NPS 4 [DN 100] ndi ang'onoang'ono akhoza kuyezedwa m'malo osavuta;
Mapaipi akulu kuposa NPS 4 [DN 100] aziyezedwa mosiyana.
Akunja Diameter
Kwa machubu a OD> 250 mm (10 mu), ngati kulondola kwapamwamba kwa OD kumafunika, kusintha kovomerezeka kwa OD ndi ± 1%.
Pa ID> 250 mm (10 mu) machubu, ngati ID yolondola kwambiri ikufunika, kusintha kovomerezeka kwa ID ndi ± 1%.
Makulidwe
Makulidwe ochepa a khoma = 87.5% ya makulidwe omwe atchulidwa.
Utali
Kutalika kwachisawawa kamodziKutalika: 4.8-6.7 mamita [16-22ft].5% ya utali wake imaloledwa kukhala yosachepera 4.8 m [16 ft], koma osachepera 3.7 m [12 ft].
Utali wowirikiza kawiri: Utali wocheperako ndi 10.7 m [35 ft] ndipo utali wocheperako ndi 6.7 m [22 ft].Maperesenti asanu mwautali amaloledwa kukhala osakwana mamita 6.7 [22 ft], koma osachepera 4.8 mamita [16 ft].
Chithandizo cha Zowonongeka Pamwamba
Kutsimikiza kwa Zolakwika
Zowonongeka zapamtunda zikachitika m'machubu opitilira 12.5% ya makulidwe a khoma kapena kupitilira makulidwe ochepa a khoma, zolakwikazo ziyenera kuchotsedwa pogaya malinga ngati makulidwe otsala a khoma ndi 87.5% kapena kupitilira apo.
Zosavulaza Zowonongeka
Kuti chithandizo chapamwamba chigwirizane ndi zofunikira za ndondomekoyi, zolakwika zotsatirazi zosavulaza ziyenera kuchotsedwa ndikupera:
1. Zizindikiro zamakina ndi ma abrasions - monga zingwe za chingwe, ziboda, zolozera, zopindika, kukanda kwa mpira, zolowera ndi nkhungu, ndi maenje, zomwe sizingadutse 1/16 mu (1.6mm) mwakuya.
2. Zosawoneka bwino, makamaka kutumphuka, zopindika, zopindika, misozi, kapena magawo akuya kuposa 5 peresenti ya makulidwe a khoma.
Kukonza Zowonongeka
Pamene zilema kapena zolakwika zimachotsedwa ndikupera, malo otsetsereka opindika ayenera kusungidwa ndipo makulidwe a khoma la chitoliro sikuyenera kukhala pansi pa 87.5% ya mtengo womwe watchulidwa.
Kukonza welds amapangidwa molingana ndi ASTM A530/A530M.
Chizindikiro cha Tube
Chitoliro chilichonse chachitsulo cha ASTM A106 chidzadziwika ndi chizindikiritso cha wopanga, kalasi yake, miyeso, ndi zidziwitso zamakalasi aNdalama kuti zizindikirike mosavuta komanso kutsata.
